from chemistry to pack
Author: Khaled Mekdour LG Energy Solution’s proprietary improvement on the basic Z-stacking electrode assembly method used in pouch-type lithium-ion batteries. It merges the traditional Z-stacking approach—where cathode and anode sheets are alternately layered with the separator in a zigzag pattern—with LG’s own Lamination & Stacking (L&S) technology and a heat-press bonding step to deliver enhanced … Read more
Isolation Tests on Assembled Cells come in a number of forms, but the intention is to check for: Although very rare, cell internal short circuits are a leading cause of battery thermal runaway. They are a major safety issue for any application of a battery pack. Hence there is a requirement to prevent them and … Read more
The cell electrode pressure is required to keep the cell operating at it’s peak performance over it’s lifetime. However, is there an optimum pressure and why exactly does the cell need it? As the cell is charged lithium ions move into the graphite anode and the cell will increase in thickness. Silicon in the anode … Read more
